<title>Detect UEFI or BIOS</title>
<description>&lt;p dir=&#34;auto&#34;&gt;Here is how you can detect if you&amp;rsquo;ve booted your computer using a UEFI BIOS or a Legacy BIOS. First, install the &lt;code&gt;dmidecode&lt;/code&gt; utility from your operating system repository. On Debian, you can:&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#282a36;&#34;&gt;&lt;code&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;1&lt;/span&gt;&lt;span&gt;apt-get install dmidecode&#xA;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;p dir=&#34;auto&#34;&gt;&lt;code&gt;dmidecode&lt;/code&gt; reports information related to the BIOS under a &lt;em&gt;type 0&lt;/em&gt; entry. A quick way to detect the BIOS mode is:&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#282a36;&#34;&gt;&lt;code&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;1&lt;/span&gt;&lt;span&gt;sudo dmidecode -t &lt;span style=&#34;color:#bd93f9&#34;&gt;0&lt;/span&gt; | grep UEFI &amp;gt; /dev/null &lt;span style=&#34;color:#ff79c6&#34;&gt;&amp;amp;&amp;amp;&lt;/span&gt; &lt;span style=&#34;color:#8be9fd;font-style:italic&#34;&gt;echo&lt;/span&gt; UEFI &lt;span style=&#34;color:#ff79c6&#34;&gt;||&lt;/span&gt; &lt;span style=&#34;color:#8be9fd;font-style:italic&#34;&gt;echo&lt;/span&gt; BIOS&#xA;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;p dir=&#34;auto&#34;&gt;On a (Legacy) BIOS system you would see:&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34;

<title>Mounting BTRFS subvolumes</title>
<description>&lt;p dir=&#34;auto&#34;&gt;If you have installed GNU/Linux with BTRFS as the filesystem, chances are that your OS installer has used &lt;strong&gt;sub-volumes&lt;/strong&gt; for the &lt;code&gt;root&lt;/code&gt;, &lt;code&gt;home&lt;/code&gt; and other mount points. &amp;#x1f5c4;&amp;#xfe0f;&lt;/p&gt;&#xA;&lt;p dir=&#34;auto&#34;&gt;You can verify this by mounting the actual root filesystem device and listing its contents:&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#282a36;&#34;&gt;&lt;code&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;1&lt;/span&gt;&lt;span&gt;&lt;span style=&#34;color:#6272a4&#34;&gt;# ls -l /mnt/&lt;/span&gt;&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;2&lt;/span&gt;&lt;span&gt;total &lt;span style=&#34;color:#bd93f9&#34;&gt;0&lt;/span&gt;&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;3&lt;/span&gt;&lt;span&gt;drwxr-xr-x &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;204&lt;/span&gt; Feb &lt;span style=&#34;color:#bd93f9&#34;&gt;22&lt;/span&gt; 13:28 @&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;4&lt;/span&gt;&lt;span&gt;drwxr-xr-x &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;180&lt;/span&gt; Feb &lt;span style=&#34;color:#bd93f9&#34;&gt;22&lt;/span&gt; 14:29 @cache&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;5&lt;/span&gt;&lt;span&gt;drwxr-xr-x &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;10&lt;/span&gt; Dec &lt;span style=&#34;color:#bd93f9&#34;&gt;2&lt;/span&gt; 10:52 @home&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;6&lt;/span&gt;&lt;span&gt;drwxr-xr-x &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;482&lt;/span&gt; Feb &lt;span style=&#34;color:#bd93f9&#34;&gt;26&lt;/span&gt; 00:00 @log&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;7&lt;/span&gt;&lt;span&gt;drwxr-x--- &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;350&lt;/span&gt; Feb &lt;span style=&#34;color:#bd93f9&#34;&gt;23&lt;/span&gt; 15:40 @root&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;8&lt;/span&gt;&lt;span&gt;drwxr-xr-x &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;14&lt;/span&gt; Oct &lt;span style=&#34;color:#bd93f9&#34;&gt;19&lt;/span&gt; 07:42 @srv&#xA;&lt;/span&gt;&lt;/span&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;9&lt;/span&gt;&lt;span&gt;drwxrwxrwt &lt;span style=&#34;color:#bd93f9&#34;&gt;1&lt;/span&gt; root root &lt;span style=&#34;color:#bd93f9&#34;&gt;1576&lt;/span&gt; Feb &lt;span style=&#34;color:#bd93f9&#34;&gt;27&lt;/span&gt; 17:18 @tmp&#xA;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;p dir=&#34;auto&#34;&gt;Here &lt;code&gt;@&lt;/code&gt;, &lt;code&gt;@home&lt;/code&gt;, &lt;code&gt;@log&lt;/code&gt; etc. are the BTRFS sub-volumes. &lt;code&gt;@&lt;/code&gt; is the OS root sub-volume.

<description>&lt;p dir=&#34;auto&#34;&gt;&amp;#x1f3a7; If you have to use a Chromebox with GNU/Linux, the sound might not work right away. To get &lt;strong&gt;Intel Corporation Sunrise Point-LP HD Audio&lt;/strong&gt; working, do do the following:&lt;/p&gt;&#xA;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#282a36;&#34;&gt;&lt;code&gt;&lt;span style=&#34;display:flex;&#34;&gt;&lt;span style=&#34;white-space:pre;user-select:none;margin-right:0.4em;padding:0 0.4em 0 0.4em;color:#7f7f7f&#34;&gt;1&lt;/span&gt;&lt;span&gt; &lt;span style=&#34;color:#8be9fd;font-style:italic&#34;&gt;echo&lt;/span&gt; &lt;span style=&#34;color:#f1fa8c&#34;&gt;&amp;#34;options snd-intel-dspcfg dsp_driver=1&amp;#34;&lt;/span&gt; &amp;gt; /etc/modprobe.d/inteldsp.conf&#xA;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;p dir=&#34;auto&#34;&gt;Once you reboot, you should be able to use Audio over HDMI or the built-in headphone jack.&lt;/p&gt;&#xA;&lt;p dir=&#34;auto&#34;&gt;&lt;a href=&#34;/+/tag/chromebox&#34; class=&#34;tag is-info is-light&#34;&gt;#chromebox&lt;/a&gt; &lt;a href=&#34;/+/tag/linux&#34; class=&#34;tag is-info is-light&#34;&gt;#linux&lt;/a&gt; &lt;a href=&#34;/+/tag/audio&#34; class=&#34;tag is-info is-light&#34;&gt;#audio&lt;/a&gt;&lt;/p&gt;&#xA;</description>
